 When there is no ImagePath value for a module it indicates
 that the module has not been installed.  Do not report an
 error to the end user for uninstalled modules.  This will
 only annoy the user and there is probably nothing the user
 can do about it.  Perhaps the user uninstalled the module
 intentionally.  The fact that there is still a HKCU key
 remaining is not an indication that the module is in use.
